Joshua Colp	3ed05badb9	core: Add stream topology changing primitives with tests. ... This change adds a few things to facilitate stream topology changing: 1. Control frame types have been added for use by the channel driver to notify the application that the channel wants to change the stream topology or that a stream topology change has been accepted. They are also used by the indicate interface to the channel that the application uses to indicate it wants to do the same. 2. Legacy behavior has been adopted in ast_read() such that if a channel requests a stream topology change it is denied automatically and the current stream topology is preserved if the application is not capable of handling streams. Tests have also been written which confirm the multistream and non-multistream behavior. ASTERISK-26839 Change-Id: Ia68ef22bca8e8457265ca4f0f9de600cbcc10bc9	9 years ago
George Joseph	0560c32375	stream: Unit tests for stream read and tweaks framework ... * Removed the AST_CHAN_TP_MULTISTREAM tech property. We now rely on read_stream being set to indicate a multi stream channel. * Added ast_channel_is_multistream convenience function. * Fixed issue where stream and default_stream weren't being set on a frame retrieved from the queue. * Now testing for NULL being returned from the driver's read or read_stream callback. * Fixed issue where the dropnondefault code was crashing on a NULL f. * Now enforcing that if either read_stream or write_stream are set when ast_channel_tech_set is called that BOTH are set. * Added the unit tests.

Joshua Colp	6cc890b880	channel: Add support for writing to a specific stream. ... This change adds an ast_write_stream function which allows writing a frame to a specific media stream. It also moves ast_write() to using this underneath by writing media frames provided to it to the default streams of the channel. Existing functionality (such as audiohooks, framehooks, etc) are limited to being applied to the default stream only. Unit tests have also been added which test the behavior of both non-multistream and multistream channels to confirm that the write() and write_stream() callbacks are invoked appropriately.

Joshua Colp	a9c15a0e4c	stream: Add unit tests for channel stream usage. ... This change adds unit tests cover the following: 1. That retrieving the first media stream of a specific media type from a stream topology retrieves the expected media stream. 2. That setting the native formats of a channel which does not support streams results in the creation of streams on its behalf according to the formats of the channel. 3. That setting a stream topology on a channel which supports streams sets the topology to the provided one. ASTERISK-26790 Change-Id: Ic53176dd3e4532e8c3e97d9e22f8a4b66a2bb755	9 years ago
Joshua Colp	6c4657e28e	stream: Add stream topology unit tests and fix uncovered bugs. ... This change adds unit tests for the various API calls relating to stream topologies. This includes creation, destruction, inspection, and manipulation. Through this a few bugs were uncovered in the implementation: 1. Creating a topology using a format capabilities would fail as the code considered a return value of 0 from the append stream function to indicate an error which is incorrect. 2. Not all functions which placed a stream into a topology set the position on the stream itself. 3. Appending a stream would cause a frack if the position provided was the last one. This occurred because the existing stream was queried but the index was outside of what the vector was currently at for size.

Joshua Colp	bab4885f1e	stream: Add media stream definition and API with unit tests. ... This change adds the media stream definition and API for accessing and using it. Unit tests have also been written which exercise aspects of the API. ASTERISK-26773 Change-Id: I3dbe54065b55aaa51f467e1a3bafd67fb48cac87	9 years ago
